[check-param-names] "Cannot read property 'name' of undefined" with type {(): void}

[wnayes]

Seeing an error similar to #529 and #576, but on 30.2.3 when linting TypeScript code like the following:

/**
 * Show a prompt.
 * @param hideButton true if button should be hidden, false otherwise
 * @param onHidden delegate to call when the prompt is hidden
 */
public async showPrompt(hideButton: boolean, onHidden: {(): void}): Promise<void>
{
}

I'd guess the issue has to do with {(): void} as the param type. (I'm aware this could be better typed as () => void or something similar 😄)

I wouldn't suspect a recent a regression of those other issues; I just haven't upgraded until recently. I'm not sure how far back the issue goes.

Expected behavior

No errors.

Actual behavior

Oops! Something went wrong! :(
